Missing 9 HP

So I was just reading about the 06 DTS models and I was wondering why the 'sport' package N* is rated at 291 HP and not 300 anymore. I don't understand why they would de-tune the engine in the sport model.

Re: Missing 9 HP

Relax. The engine makes the same power. The rating system and corrections per SAE changed and the engine is rated at slightly less power per the new procedures. No change in the engine or the actual power output.
